This reworks cgroups support so we have one variable in rc.conf for each
controller instead of each setting.
Also we add support for all of the possible cgroup controllers.
I would like to thank Alexander Vershilov for his help with testing and
reworking this code.

Using setfont directly to save the font prevents breakage
when a distro stores consolefonts in a location other than
/usr/share/consolefonts such as Arch which stores them in
/usr/share/kbd/consolefonts

sh/rc-cgroup.sh.in: new script to handle cgroup processing
sh/rc-cgroup.sh.in: do not use grep or cut (modification by William Hubbs)
sh/runscript.sh.in: use the cgroup script
If an init script or service was upgraded while it was running and the
settings for the pid file, command and process name were changed, it
would not be possible to stop the old service.
Runscript now saves the values it used to start the service and re-uses
them to stop the service.

In order to make migration from /lib*/rc/init.d to /run/openrc possible
without rebooting, the migration script creates a symlink from
/run/openrc to /lib*/rc/init.d. We were trying to remove it on the next
reboot, but this is not possible since / is ro when /run is mounted.

This doesn't affect us on gentoo, but on archlinux, which has done the
/usr merge, OpenRC was looking for /run under PREFIX. /run is always at
the root level, so it shouldn't have prefix appended to it.

This commit was modified by William Hubbs as follows:
- The paths in the cgroup fs were put into variables to ease
maintenance.
- Documentation was added to rc.conf.Linux.
- The services were added originally to openrc/svcname cgroups under the
controller cgroups, but this left an "openrc" cgroup which was unused.
Now they are added to individual cgroups with the name openrc_${RC_SVCNAME}.
systemd allows the final arg in tmpfiles to contain spaces. Using the read()
call to set the variables includes all trailing components in $arg so it
doesn't get cut off.

We should use the "command" shell builtin to execute a binary from
within the wrapper with the same name. Hard coding the path to the
binary makes our test suite fail.
Now that the tmpfiles.d code is more tested, actually call it from
init.d. It assumes that /run is already available when it runs.
Please note it runs TWICE.
- During sysinit, ideally just after /dev/shm is created, but before
udev has started. After udev is also acceptable, but not ideal.
- During boot, ideally just after localmount has completed.

By design, restart is hard coded to run stop followed by start along
with all of the pre/post functions associated with them. Restart doesn't
need its own pre/post functions since it is possible to make any
function in an init script behave differently for a restart command by
testing against the RC_CMD environment variable.
Mount can't be used in vservers, but /run is still needed. So we create
the directory and clear it out instead of mounting a tmpfs in that
situation.

If you are not using linux, this should not affect you.
If you are using linux, from this point forward, openrc requires the
/run directory to be a mounted tmpfs. If it is, you can run
@LIBEXECDIR@/sh/migrate-to-run.sh as root to migrate your dependency
tree and state information to the new location. If it is not, you must
create the /run directory as root with permissions 755 then reboot your
system.

This message was being taken by some users as an error, so I have
removed the part about "skipping..." Hopefully this will make the
message less alarming.
There were a couple of places where we were sourcing functions.sh in
@SYSCONFDIR@/init.d. This is only a backward compatibility symlink, so
it should not be used for openrc. The correct place to source this from
is @LIBEXECDIR@/sh.
We already have a special case for depend processing, so we should
change the working directory there only. This prevents us from forcing
all init scripts to be run in the init directory.
Enter the service directory, like gendeps.sh does, to make sure globs are
expanded in it rather than in /. That makes sure that globbing like "need *"
will end up in all files of the init.d directory.

Upstream has clarified via IRC:
- hardcoding /usr/lib/ is an explicit choice. It should NOT consider
$libdir at all.
- The z/Z relabel types should call restorecon, not chcon.
- Whitespace is not allowed in tmpfiles.d/*.conf path entries,
but is allowed in globs results. Fixed quoting of path arguments for
this.

This is the baseline support for tmpfiles.d.
Still missing:

- LIBDIR vs multilib systems, pending upstream clarification
- Whitespace in paths?
- Clean support not implemented

The commands defined in the extra_commands variable do not depend on
whether the service is stopped or started, so it is valid to run them in
chroot environments.
Also, add a note to the runscript man page about the commands in
extra_commands being able to run whether or not the service is started.

Openrc will create a cgroup hierarchy called openrc which will have all
services it starts and all subsystems attached to it. If you need other
groups/hierarchies, please use libcgroup.
The kernel documentation states that a cgroup file system should not be
mounted here, but a tmpfs.
This also means that we should not create a group for each process, but
we should allow the user to specify which group a process should be
assigned to. The rc_cgroup variable will be used for this purpose.
For more information, see /usr/src/linux/Documentation/cgroups/cgroups.txt.
When a CGroup is created, we need to copy cpuset.cpus and cpuset.mems
from the new group's parent into the new group before we can attach any
processes to it.
Some variable references were written as $(foo), but the majority were
written as ${foo}. This commit changes all of the variable references
to using braces.
The tree contained many operating system specific Makefiles which were
being included in other Makefiles. This commit removes those and adds
the code to the makefiles which included them using make's conditional
processing.

Openrc uses the extra_commands and extra_started_commands variables to
list extra commands for services. Also, it supports the opts variable
which is used to assist migration from baselayout-1.
I am adding this warning to encourage switching from opts to
extra_commands/extra_started_commands.
I would like to remove support for opts eventually.
The extra_net_fs_list variable was not being included as it should have
been for the net file systems because it was being expanded before it
was set by the user.

The previous test assumed that we could always rely on the minor fault
counter to change between reads of /proc/self/stat, but we found that
this is not the case.
The new test compares two reads of /proc/self/environ for which we have
set the same environment variable to two different values.
If the comparison shows the two reads have the same contents, we know
that /proc is not working.

Previously we checked if /proc was alive by reading /proc/uptime twice
with a 1 second sleep between calls, so that it had time to update.
This got a complaint of an entire 1 second delay, so we improve the
check to be much faster without sleep. We cannot continue to use
/proc/uptime as it only has a 10ms resolution.

OpenRC version is now stored as plaintext in /libexec/rc/version

Split halt.sh into halt, killprocs, romount and savecache services.
The reboot runlevel is removed but mapped to shutdown.
The halt script should be moved to the sysvinit package.
mounting various bits in /dev and /sys.
init.sh JUST mounts /lib/rc/init.d (and /proc for Linux systems)
To make development of this easier we now return an empty RC_STRINGLIST
instead of a NULL for empty things.
If you don't have a udev init script installed, don't reboot your box OR
roll back to an older OpenRC version.
